Question

我已经使用oledb提供程序（SQLOLEDB和SQL Native OLEDB提供程序）创建了一个示例应用程序。

案例1：提供者= SQLOLEDB

hr = ::CoInitializeEx(NULL, COINIT_MULTITHREADED);
hr = cADOConnection.CreateInstance(__uuidof(Connection));
CString con_string = "provider=SQLOLEDB;server=MYPC;Database=MyDB";

CString SSlcon_string = "provider=SQLOLEDB;Encrypt=true;TrustServerCertificate=true;server=MYPC;Database=MyDB";
CString userName = "sa";
CString Password = "sa";
BSTR bsConnection = /*con_string*/SSlcon_string.AllocSysString();
BSTR uName = userName.AllocSysString();
BSTR uPassword = Password.AllocSysString();

hr = cADOConnection->Open(bsConnection, uName, uPassword, adConnectUnspecified);
printf("connection has been established");
VARIANT vaNoRecords;
memset(&vaNoRecords, 0, sizeof vaNoRecords);
CString sql = "SELECT * FROM salary";
BSTR query = sql.AllocSysString();
_RecordsetPtr rs;
rs = cADOConnection->Execute(query, &vaNoRecords, adCmdText);
printf("connection has been established\n");

结果：如果在服务器计算机上安装了证书，则无论启用哪个连接都是安全的连接字符串中的Encrypt = true和TrustServerCertificate = true。

案例2：Provider = SQLNCLI10.1（SQL本机客户端oledb提供程序）

HRESULT hr;
hr = ::CoInitializeEx(NULL, COINIT_MULTITHREADED);
hr = cADOConnection.CreateInstance(__uuidof(Connection));
CString con_string = "provider=SQLNCLI10.1;server=MYPC;Database=MyDB";

CString SSlcon_string = "provider=SQLOLEDB;Encrypt=true;TrustServerCertificate=true;server=MYPC;Database=MyDB";
CString userName = "sa";
CString Password = "sa";
BSTR bsConnection = con_string/*SSlcon_string*/.AllocSysString();
BSTR uName = userName.AllocSysString();
BSTR uPassword = Password.AllocSysString();
hr = cADOConnection->Open(bsConnection, uName, uPassword, adConnectUnspecified);
printf("connection has been established");
VARIANT vaNoRecords;
memset(&vaNoRecords, 0, sizeof vaNoRecords);
CString sql = "SELECT suppliernumber, name1 FROM zrs_supplier";
BSTR query = sql.AllocSysString();
_RecordsetPtr rs;
rs = cADOConnection->Execute(query, &vaNoRecords, adCmdText);
printf("connection has been established\n");

结果：如果在服务器计算机上安装了证书，则无论启用哪个连接都是安全的连接字符串中的Encrypt = true和TrustServerCertificate = true。结果与上面相同。

在这两种情况下我都有同样的行为。我在这里遗漏了什么？任何建议将不胜感激？ Original question

用

替换连接字符串

CString SSlcon_string = "provider=SQLOLEDB;Use Encryption for Data=True;server=MYPC;Database=MyDB";

其余步骤将相同。在客户端计算机上安装相同的证书（存在于服务器上）＆＃34; 被盗的根证书颁发机构＆＃34;文件夹中。

如果服务器和客户端都具有相同的证书，那么将建立连接（SSL连接），否则将失败。

使用Microsoft OLE DB提供程序和SQL Native OLE DB提供程序建立数据库连接
